If you thought your face was the only betrayer of your age, we've got a news flash: Dull, damaged hair screams, "Don't bother to card me!" Here, the best pro tips for covering grays, adding shine, and plumping limp strands.

Yes, bangs can make you look younger; the trick is to find the right shape and cut that shaves off years without making you look like the world's tallest preschooler. Consider your face shape: Long, thin faces can handle thicker, blunt-cut bangs. Rounder, fuller faces need a slightly longer, choppier style. (You can achieve this by having your stylist cut into the ends with scissors.) Side-swept bangs that fall below the brows accentuate cheekbones and minimize large foreheads—and can be flattering on just about anybody.
